Buying shoes and trainers: how to choose a pair suited to how you use them

Buying shoes and trainers online may seem straightforward, but an appealing photo tells you little about fit, grip or care. A trainer suitable for everyday wear will not necessarily be comfortable for running. Similarly, a shoe described as “waterproof” may be less suitable for prolonged rain than you expect.

Use this practical checklist to avoid disappointing purchases and compare women’s trainers, men’s trainers, children’s shoes, running shoes and walking shoes based on verifiable features.

Common pitfalls when buying shoes online

1. Using a fashionable shoe for the wrong activity

A low-profile lifestyle trainer, such as a Dunk Low, Converse or Vans Old Skool, is designed for everyday wear. Its construction and sole are not the same as those of running shoes or trail-running shoes. If you use a casual model for long-distance running, you may find that it offers insufficient cushioning, ventilation or grip on uneven terrain.

Start by considering how you will use the shoes: work, city wear, walking, sport, running or unpaved paths. Do not choose sports shoes based on colour or brand name alone.

2. Confusing “comfortable” with a good fit

Comfort is not a universal quality. A soft insole may feel pleasant, but if the toe box is too narrow or your heel slips, the shoe remains impractical. Always check the size chart, foot length and available width. Some models come in standard or narrow versions, which is more relevant than simply choosing your usual EU size.

3. Water-repellent is not the same as waterproof

Product descriptions distinguish between a water-repellent construction and a membrane that, according to the product information, provides protection in wet conditions. Also check the shoe’s height, seams and care instructions. Despite treated materials, a low trainer may still allow water to enter at the sides.

Which specifications should you check?

Fit, size and toe room

Measure both feet at the end of the day and compare the measurements with the model’s size chart. Pay attention to:

  • Foot length in millimetres, not just EU size.
  • Toe room, particularly for running shoes and walking shoes.
  • A secure heel hold without pressure points.
  • The right width: standard, narrow or a model with a wider toe box.
  • Thicker socks for winter or walking shoes.

Extra checks are important for children’s shoes. Feet grow, but an oversized shoe can slip and affect the walking experience. Check the fastening, inner length and width before ordering.

Sole, grip and terrain

A rubber sole generally provides grip, but the tread determines what the shoe is suitable for. A flatter tread is better suited to use on pavements and streets. Trail-running shoes often have a deeper tread for mud, loose ground and stones. For football or lacrosse, studs are specifically designed for the playing surface.

Look out for these technical terms in the product information:

  • EVA midsole: often used for cushioning and resilience.
  • Rubber outsole: check the tread and intended terrain.
  • Contagrip or ROCKYTEC: brand names for sole technologies; the precise properties are set out in the brand’s product description.
  • FG studs: intended to provide grip on natural grass, according to the model’s product information.

According to Salomon’s product description, the XA Pro 3D v9 GTX has a Contagrip outsole and 3D Advanced Chassis. This makes this type of shoe a more logical choice for walking and trail use than a casual trainer, but the final decision depends on the terrain, distance and fit.

Material, ventilation and care

Textile and mesh are often lightweight and breathable. Leather and synthetic materials can provide a more robust upper, but require different care. Check whether the shoe is machine washable. Many models with electronic components, special membranes or leather sections may only be cleaned with a damp cloth.

A GORE-TEX membrane, as listed for the Salomon XA Pro 3D v9 GTX, is described as waterproof in the product information. The brand’s product information presents this as a product specification, and you should follow the care instructions to preserve these properties as effectively as possible.

Frequently asked questions about buying shoes and trainers

Which shoes are suitable for everyday wear?

For everyday wear, you can choose from lifestyle trainers such as Nike trainers, Converse trainers, Vans Old Skool or Skechers shoes. Pay particular attention to fit, ventilation, sole comfort and how many hours you will be walking. For rain or winter, waterproof shoes or models with a treaded sole are more practical than thin canvas trainers.

How long do shoes typically last?

Their lifespan depends on the material, how often they are worn, body weight, terrain and care. Shoes worn every day wear out faster than a pair used in rotation. Check the sole, seams, heel and cushioning regularly. Replace a pair when the sole becomes smooth, the upper tears or the fit visibly changes.

Are more expensive sports shoes always a good choice?

Not necessarily. A higher price may be linked to the materials, brand, membrane or technical construction, but above all, the shoe must suit your activity and feet. Compare objective features such as sole type, upper material, fastening, weight, water protection and size chart.
